Abstract

A signal transmitting circuit may include: a logic gate coupled in series to transmit a signal, and operated by a first supply voltage; a pre-driver circuit suitable for generating a pull-up control signal and a pull-down control signal in response to the transmitted signal, wherein a second supply voltage having a level greater than the target level of the first supply voltage is used to generate the pull-up and pull-down control signals; a first NMOS transistor suitable for pulling up an output node using the first supply voltage, in response to the pull-up control signal; a second NMOS transistor suitable for pulling down the output node using a pull-down voltage, in response to the pull-down control signal; and an initialization circuit suitable for initializing the pull-up and pull-down control signals when the level of the first supply voltage is less than a reference value, before a power-up signal is enabled.
